Description

[Detailed explanation of the idea] The present invention relates to improvement of the body structure of an automobile.

To eliminate various problems that conventionally occur in automobiles by joining the lower part of the front pillar and the deck member by arc welding or gas welding, such as variations in joint strength, deterioration of workability, and deterioration of rust prevention treatment due to heat. For this purpose, for example, as shown in FIG. 1, an outwardly projecting flange 6 is provided at the lower part of the outer panel 4 of the front pillar 2, and a deck member (not shown) is connected to the flange 6 by spot welding. The car body structure is known.

However, in the above-mentioned conventional structure, although the second outer panel 8 is connected to the front pillar 2, water intrudes into the pillar 2 from the cut-back portion A at the rear end of the flange 6, and the infiltrated water There was a risk that the liquid would enter the vehicle interior through the gap between the deck member (not shown) and the portion B of the inner panel 10 of the pillar 2.

The present invention was devised in view of the above, and includes a front pillar outer panel that is combined with a front pillar inner panel to form a front pillar, a front deck member that is combined with the front pillar outer panel, and a front deck member that is connected to the front pillar in the longitudinal direction of the vehicle body. An upper frame having a cross-sectional shape in the vehicle width direction that is placed and connected so as to extend, and a connecting panel that is connected to the front deck member and the front pillar outer panel, further comprising: A flange that extends upwardly and integrally with the vertical wall of the front pillar outer panel that extends toward the front of the vehicle body, and an inner edge of the flange that extends inward from the front pillar inner panel. a sealer applied to a joint portion joined to a lower surface of the front deck member in the above, and the joining panel has an upper end thereof attached to an outer edge of the front deck member extending further outward from the joint portion. The lower end portions are respectively coupled to the vertical wall portions of the front pillar outer panel near the flange, and a first closed section having a triangular cross section is formed by the coupling panel, the flange, and the front deck member; A second closed section section adjacent to the upper part of the closed section section and having a rectangular cross section is formed by the front deck member and the atsupa frame, and further a drainage port is formed between the atsupa frame and the front deck member. The gist of this article is an automobile body structure characterized by:

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 2 to 5.

In the figure, reference numeral 20 indicates a front pillar, which is formed by a front pillar outer panel 22 and an inner panel 24 to form a closed cross section.
Reference numeral 26 designates a front deck member, 28 designates an upper frame having a closed cross-sectional shape in the vehicle width direction and is mounted and connected to the front deck member 26 so as to extend in the longitudinal direction of the vehicle body, and 30 designates a connection panel. A portion of the vertical wall portion of the front pillar outer panel 22 extends further forward of the vehicle body than the front pillar inner panel 24, and is further integrally continuous with this extended vertical wall portion and extends inside the vehicle body and upwardly. A bent and extended flange 32 is formed. The tip edge 32a of the flange 32 is joined to the lower surface of the deck member 26 on the inside of the vehicle from the front pillar inner panel 24 by spot welding. The joining panel 30 has a flange 34 at its upper edge that extends outward from the vehicle body, and the flange 34 is joined to the lower surface of the side edge of the deck member 26 by spot welding, and the lower edge It is joined to the outer surface of the front pillar outer panel 22 by spot welding, and the flange 32 of the outer panel 22, the deck member 26 and the joining panel 30
This forms a first closed section having a triangular cross section. In the upper frame 28, a flange 36 on the inside of the vehicle body is joined to the deck member 26 together with a flange 32 of the front pillar outer panel 22 by spot welding, and a flange 38 on the outside of the vehicle body is joined to the deck member 26 on the flange 34 of the panel 30.
They are joined together by spot welding, thereby forming a second closed section having a rectangular cross section above and adjacent to the first closed section. The upper frame 28 also has drainage ports 40 and 42 for draining rainwater on the deck member 26.
A drip channel (not shown) coupled to the outer surface of the front pillar outer panel 22 is formed so as to be continuous with the flange 34 of the coupling panel 30. Therefore, it is preferable that the outer edge of the flange 34 of the coupling panel 30 also has a flange (not shown) directed upward. Although not shown, the front edge of the front deck member 26 and the front flange 44 of the outer panel 22 are joined to the upper edge and side edge of the dash panel by spot welding, respectively.

According to the above configuration, the first closed cross section formed by the flange 32 of the front pillar outer panel 22, the coupling panel 30 and the deck member 26, and the second closed cross section formed by the upper frame 28 and the front deck member 26. Since it has a double closed cross-section structure, it has the effect of significantly improving the rigidity of the vehicle body compared to conventional structures with a small number of parts.

Furthermore, by making the first closed cross-section portion triangular, the angle formed between the vertical wall portion of the front pillar outer panel 22 and the flange 32 can be made obtuse, so that when the flange 32 is drawn and formed, it is possible to form an obtuse angle. This has the effect that a flange 32 that is long in the vehicle width direction can be easily obtained without increasing the depth. (If the flange is bent at right angles as in the past, the drawing depth must be increased in order to obtain a long flange, which tends to cause processing defects such as wrinkling and breakage.) Since the tip edge 32a of the flange 32 is connected to the deck member 26 on the inside of the vehicle from the front pillar inner panel 24, it is easy to apply sealer to the joint, and the first closed cross section is triangular. As a result, the flange 32 forms a slope with the inner side of the vehicle raised higher, so water that flows from above the front pillar 20 over the upper surface of the front pillar outer panel 22 and enters the upper surface of the flange 32 actively flows toward the outer side of the vehicle. The water is discharged from the gap between the spot welds between the front pillar outer panel 22 and the coupling panel 30, and the sealer has the effect of sufficiently preventing water from entering the vehicle interior.

Furthermore, since the drainage passages 40 and 42 are formed between the deck member 26 and the atsupah frame 28, which is the two series of closed section structure parts with increased rigidity of the vehicle body, rainwater inside the deck member 26 is drained from the passage 4.
It also has the effect that it can be effectively discharged to the outside via the tubes 0 and 42.

Although the deck member 26 is formed of one panel in the above embodiment, it is of course possible to use a well-known deck member formed of a plurality of panels.
